Robust Unit Commitment for Integrated Electricity and Heat Systems Considering Carbon Emissions

Year: 2025

Type: conference-paper

Abstract: In northern China, the primary method for winter heating is through combined heat and power (CHP) centralized heating systems. However, the heat-driven operational model significantly restricts the integration of wind power, leading to substantial curtailment. The heating networks' pipelines have significant thermal storage potential. Leveraging these thermal storage characteristics in the dispatch of integrated electricit-yheat systems (IEHS) can enhance the operational flexibility of heating units and improve the system's ability to integrate large-scale wind power. The variability of wind power and heat load introduces uncertainties in system dispatch. To address this, a two-stage robust optimization dispatch method is developed, incorporating carbon emission costs to optimize the configuration of both the electricity power network (EPN) and the district heating network (DHN). A numerical test is performed using an IEHS consisting of a six-bus EPN and a six-node DHN. The findings demonstrate that the proposed optimization method effectively utilizes thermal energy storage benefits, facilitates wind power integration, and supports the low-carbon and efficient operation of the IEHS.
